Crossover trial of partial shift working and a one in six rota system for house surgeons in two teaching hospitals.

The objective of this study was to compare an on call rota and partial shift working pattern for house surgeons in two hospitals. The study was conducted using a crossover trial of working both systems for 6 weeks each in two groups of newly appointed house surgeons. Assessment was by questionnaire to house surgeons, consultants, registrars, nursing staff and patients. The study took place at the departments of general surgery at Guy's and Lewisham Hospitals, London. A total of 12 house surgeons attached to four surgical firms and their consultants and registrars were the subject of our study. In addition the permanent nursing staff on designated general surgical wards and those patients of greater than 48 h stay on those wards on the day of assessment took part. Expectations of reduced fatigue levels using the partial shift system were not fulfilled. In contrast, this working pattern led to perceived disruption of the running of the surgical firms and demoralization of the house surgeons. Standards of patient care were, however, equally high using a rota or partial shift system. This comparison of a partial shift working pattern to an on call rota of similar average weekly hours demonstrated a marked preference for an on call rota from both medical and nursing staff although patients found both systems acceptable.
